Combine flour, baking soda, and salt in a small bowl and set aside. Cream together butter and sugars. Beat in pudding mix until blended. Add the eggs and vanilla and mix well. Add the flour mixture and mix to combine. Stir in cookies n' cream pieces and chocolate chips.

Place golf ball sized dough balls on a cookie sheet (I use a baking stone). Bake at 350 degrees for 8 minutes. Do not over-bake! Let cookies cool for 5 minutes on cookie sheet before moving to a cooking rack. Store in air-tight container (I suggest doing this while they're still a little warm if you like your cookies on the chewy side)
